Age-related changes in the nervous system

aging of the human body
with age in humans, their brain and nervous system go through natural changes.Brain and spinal cord lose nerve cells and weight.Nerve cells can begin to transmit messages more slowly than in the past.body waste may accumulate in tissues of the brain as the nerve cells are destroyed, which leads to an abnormal structure called plaques and tangles.Fat brown pigment (lipofuscin) can also accumulate in the nervous tissues.At one - degree, it's blocking nerve impulses to the brain from other organs and organ systems.
breakdown of the nerves can affect the senses.Perhaps some reflexes are diminished or completely lost, which leads to a movement and safety problems.
Some slight slowing of thought and memory seem to be a normal part of aging.Although these changes are natural, many people have a misconception about the type and extent of these changes.A common myth is that all elderly people are scattered.Or, many people blame aging increasing confusion when it can actually be
These changes are not the same for everyone.Some people have a lot of physical changes in the nerves and brain tissue, others have few other changes.Some people have atrophy and plaques, some plaques and tangles, and some other pathological changes, such as thought disorder associated with Alzheimer's disease.
In addition, these changes are not always clearly related to the impact on our ability to think.There are many examples of people with the most severe symptoms have fewer plaques and tangles than people with mild to moderate symptoms.
nervous system of elderly
Dementia and severe memory loss is not a normal aging process.They may be caused by degenerative brain diseases such as Alzheimer's disease.
Delirium can complicate dementia, but often due to diseases that are not associated with the brain, which can cause changes in thinking and behavior.For example, almost any infection can cause an older person to confusion.Certain drugs can also cause this.
poorly controlled blood sugar (glucose) in people with diabetes is another common cause of temporary difficulties with thinking and behavior.The rise and fall in blood sugar levels can affect your ability to think sensibly.
Discuss any significant changes in memory, thinking, or ability to perform tasks with your doctor, especially if these symptoms occur suddenly or along with other symptoms.Change of thinking, memory, or behavior is an important symptom, if it is different from the usual pattern of your behavior or affect your normal life.
prevention of age changes in the brain
There is some evidence that both physical and mental exercises help to maintain cognitive abilities.Reading books, solving crossword puzzles, and participating in stimulating conversations - as well as regular exercise can help keep your brain as sharp as possible.However, this strategy has not been proven 100%, unfortunately.
